Here are some common ranges based on house size: 1,000 square-foot house: $4,000-$7,000 3,000: $12,000-$21,000 4,000: $16,000-$28,000 How Do I Calculate Foundation Costs? The price factors in building a foundation are: * Type - Slab designs are cheapest at up to $21,000. Basement foundations can run as much as $175,000. * Soil tests - $10-$100 per test. Tests tell your builder about the state and contents of soil. Data helps them pick the right materials and technique. * Depth - Can raise price by up to 75%. Digging below frost line protects against freeze and thaw damage. Colder climates, wet soils and hillsides need to be deeper. If your pro might hit bedrock, hire a structural engineer * Building codes - Local rules may add expenses that vary by area. Ask your builder about rules and prices that may impact project. * Drainage and moisture. Poured slabs will need sealant. Crawl spaces need to be sealed. Basement may need sump pump or drain tiles
